In this letter, a novel phase shifter with high selectivity is proposed and developed. It is divided into the main line together with the reference line. Firstly, the main line is a bandpass filter implemented by using the new coupled feed lines loading stub‐loaded coupled‐line resonators. Varying the coupling coefficient and the electrical length of the loaded branch can reasonably allocate the passband and transmission zeros/poles. Then, the reference line is a uniform microstrip line with an electrical length related to the phase shift degrees. Compared with conventional phase shifters, this phase shifter has the advantages of good frequency selectivity, as well as easy adjustment of the phase shift value. Finally, the phase shifter of 45°~180° are designed, simulated, and the value of 180° is fabricated and measured. The simulations are in good agreement with the actual measurements.

“…The magnetized ferrite materials are widely used in tunable microwave devices due to their effective permeability properties that tune by changing DC magnetic bias. [1][2][3][4][5] Along with the advancement of the substrate integrated waveguide (SIW) technology, many ferrite-loaded SIW components, such as tunable filters, 6 tunable antennas, [7][8][9] phase shifters, 10 isolators, 11 tunable cavity resonators, 12 and chamber amplifiers have been reported in recent years.…”

In this paper, a miniaturized substrate integrated waveguide filter on the magnetized ferrite is presented. The proposed filter has a small size, high power transmission capability, relatively good bandwidth, and tunable frequency bandwidth. This filter is tunable due to the magnetic bias applied to the ferrite substrate. Compared to the tunable filters reported in previous references based on PIN diode, varactors, and mechanical changes, the proposed filter has a relatively wide adjustment on the operation frequency. Using this method dramatically reduces the complexity of the external control system. This tunable filter is optimized using the Ansoft HFSS software and then fabricated. The measured operating frequency of the filter is tunable from 5.3 to 7.15 GHz by changing the magnetic bias from 100 Oe to 1100 Oe. In the frequency range of 5.55 to 6.95 GHz, an insertion loss of less than 1.1 dB and a return loss of better than 20 dB are achieved. A good agreement between the simulation and experimental results was achieved.

“…Over the ferrite CRLH TLs, it has proven that coplanar waveguide based devices needs smaller DC magnetic bias compared to microstrip configuration [7] . Examples for these devices include tunable/nonreciprocal couplers, resonators, circulators, phase shifter [13][14][15][16][17][18][19][20][21][22][23][24][25][26] and antennas [27,28] .…”

This paper introduces different varieties of novel composite right / left handed metamaterials devices with novel magnetic operation properties. The reported devices are discussed in terms of their theoretical. The reported devices have the advantages of their small size, multi frequency band in addition to broadband operation (≈60 %) compared to their conventional design. Moreover, these devices are designed to illustrate novel magnetic properties such as their tuning and non reciprocity operation capabilities. Theoretical explanations supported by simulation results of presented devices confirmed the operation of a tunable and nonreciprocal coupler and tunable transformer. The novelty and advantage of the reported devices are their combined properties of compactness and nonreciprocity. Furthermore the devices require very low external DC magnetic bias due to its much lower demagnetization compared to the microstrip configuration. Accordingly, the devices can be applied in many RF front end novel applications such as circulators and isolators.
